Class yii\base\View

Adds a placeholder for dynamic content.

This method is used internally to implement the content caching feature.

This method is invoked right after renderFile() renders a view file.

The default implementation will trigger the EVENT_AFTER_RENDER event. If you override this method, make sure you call the parent implementation first.

This method is invoked right before renderFile() renders a view file.

The default implementation will trigger the EVENT_BEFORE_RENDER event. If you override this method, make sure you call the parent implementation first.

Begins recording a block.

This method is a shortcut to beginning yii\widgets\Block.

Begins fragment caching.

This method will display cached content if it is available. If not, it will start caching and would expect an endCache() call to end the cache and save the content into cache. A typical usage of fragment caching is as follows,

if ($this->beginCache($id)) {
    // ...generate content here
    $this->endCache();
}

Begins the rendering of content that is to be decorated by the specified view.

This method can be used to implement nested layout. For example, a layout can be embedded in another layout file specified as '@app/views/layouts/base.php' like the following:

<?php $this->beginContent('@app/views/layouts/base.php'); ?>
//...layout content here...
<?php $this->endContent(); ?>

See also yii\widgets\ContentDecorator.

Marks the beginning of a page.

Ends recording a block.

Ends fragment caching.

Ends the rendering of content.

Marks the ending of a page.

Evaluates the given PHP statements.

This method is mainly used internally to implement dynamic content feature.

Finds the view file based on the given view name.

Returns a list of currently active dynamic content class instances.

Returns a list of placeholders for dynamic content. This method is used internally to implement the content caching feature.

Initializes the view component.

Removes a last class instance supporting dynamic contents from a list of currently active dynamic content class instances.

Adds a class instance supporting dynamic contents to the end of a list of currently active dynamic content class instances.

Renders a view.

The view to be rendered can be specified in one of the following formats:

• path alias (e.g. "@app/views/site/index");
• absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the view path of the application.
• absolute path within current module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the view path of the current module.
• relative view (e.g. "index"): the view name does not start with @ or /. The corresponding view file will be looked for under the view path of the view $context. If $context is not given, it will be looked for under the directory containing the view currently being rendered (i.e., this happens when rendering a view within another view).

See also renderFile().

Renders dynamic content returned by the given PHP statements.

This method is mainly used together with content caching (fragment caching and page caching) when some portions of the content (called dynamic content) should not be cached. The dynamic content must be returned by some PHP statements.

Renders a view file.

If $theme is enabled (not null), it will try to render the themed version of the view file as long as it is available.

The method will call yii\helpers\FileHelper::localize() to localize the view file.

If renderer is enabled (not null), the method will use it to render the view file. Otherwise, it will simply include the view file as a normal PHP file, capture its output and return it as a string.

Renders a view file as a PHP script.

This method treats the view file as a PHP script and includes the file. It extracts the given parameters and makes them available in the view file. The method captures the output of the included view file and returns it as a string.

This method should mainly be called by view renderer or renderFile().

Sets a list of placeholders for dynamic content. This method is used internally to implement the content caching feature.
